Chase's car used 4 gallons of gas to drive 86miles. How many miles did chase drive using 2 gallons? And how many gallons did chase use driving 215miles?

43 mi & i think its 107.5 gal

Step-by-step explanation:

4 gal= 86 mi

4/2=2   86/2=43

2 gal= 43 mi

to get the 107 i just divided 215 by 2

1) the property is   ixi = a ⇔x = a   o x = -a

4(x-5)+3= 15⇒4x-20+3 = 15⇒4x-17= 15⇒4x = 15+17⇒4x = 32⇒x =32/4= 8

4(x-5) +3= -15⇒4x-20 +3 = -15⇒4x-17= -15⇒4x =-15+17⇒4x = 2⇒x =2/4= 1/2

the values are x =8 and x = 0,5
